Embodiment 1
[0020] Liquid chitosan compound fertilizer formula is: 50g / L, Zn 2+ 200mg / L, Al 3+ 100mg / L, pectin 8g / L, and the rest is water.
[0021] Liquid water-soluble fertilizers are prepared by:
[0022] (1) After 150 parts of corn stalks, 10 parts of animal carcasses and 120 parts of human excrement were harmlessly treated, 5 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 23 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;
[0023] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 70:15:0.2:0.1:0.005, and 1 part of the mixture is mixed with 30 parts of the biomass fermentation broth After filtering.
Embodiment 2
[0025] The liquid chitosan compound fertilizer formula is: low molecular weight chitosan 30g / L, Zn 2+ 150mg / L, Al 3+ 80mg / L, pectin 8g / L, and the rest is water.
[0026] Liquid water-soluble fertilizers are prepared by:
[0027] (1) After harmless treatment of 100 parts of corn stalks, 20 parts of animal carcasses and 80 parts of human excrement, 3 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 20 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;
[0028] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 66:20:0.5:0.1:0.005, and 1 part of the mixture is mixed with 25 parts of the biomass fermentation broth After filtering;
Embodiment 3
[0030] Liquid chitosan compound fertilizer formula is: low molecular weight chitosan low molecular weight chitosan 20g / L, Zn 2+ 120mg / L, Al 3 + 150mg / L, pectin 8g / L, the balance is water;
[0031] Liquid water-soluble fertilizers are prepared by:
[0032] (1) After 200 parts of corn stalks, 18 parts of animal carcasses and 150 parts of human excrement were harmlessly treated, 5 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 30 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;
[0033] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 76:14:0.2:0.1:0.0004, and 1 part of the mixture is mixed with 20 parts of the biomass fermentation broth After filtering.
